Large tree with rather irregular, round crown, 15 - 25 m tall. The crown is formed by heavy boughs. Mature bark light grey with deep, longitudinal grooves. The imparipinnate leaf grows 20 - 30 cm long and consists of 5 - 9, occasionally 11 leaf segments. These are ovate to oval and 8 - 12 cm long. After the leaf development, the male catkins and the smaller female flowers appear, the latter in groups of 2 or 3. The blossoms are fairly inconspicuous. The distinguishing feature of ‘Guillot’ is that this cultivar is sterile, so will bear no nuts. Highly suitable for use in parks, wide avenues and open verges. Roots very deeply and much prefers easily penetrable, open soil.
